Abstract

The invention discloses a biological sample treating instrument. The biological sample treating instrument comprises an instrument supporting frame, hydraulic cylinders, a temperature module, a stirrer, a central control system, an X-Z two-axial plane moving device and a human-computer interface, temperature control is carried out on a solution in the hydraulic cylinder by virtue of the central control system, the central control system controls the stirrer to stir the solution in each hydraulic cylinder, and the X-Z two-axial plane moving device is arranged on the instrument supporting frame, the central control system controls the tail end of a moving part of the X-Z two-axial plane moving device to output X-Z two-axial planar motion, so that a glass slide frame can be hoisted in each hydraulic cylinder, location switching of the glass slide frame is carried out among the different hydraulic cylinders, the glass slide frame moves in different hydraulic cylinders, and batch treatment on a biological sample is realized. The biological sample treating instrument has the advantages that various treatment can be carried out on the sample adhered onto the surface of a glass slide in batch, efficiency is high, repeatability and consistency are good, size is small, production cost is low, mounting and maintenance are convenient, and energy consumption is low.

Description

technical field [0001] The invention relates to a biological experiment instrument, which is especially suitable for processing biological samples in different liquids or reagents, and is applied in the technical field of biophysical and chemical analysis and testing. Background technique [0002] In conventional genetic and pathological analysis, it is necessary to stain the sample to be analyzed to facilitate further analysis in the later stage. The dyeing process generally includes a series of processing processes such as aging, digestion, fixation, denaturation and dyeing. Each process requires specific reagents and specific temperatures for a certain amount of time. [0003] Chromosomal specimens are fixed on glass slides. After G-banding treatment, bands with different width and brightness appear on the chromosomes. Chromosome karyotypes can be analyzed under a microscope. The G-banding process includes four steps: trypsin digestion, digestion stop, Giemsa staining a...
